Experimental studies of the electron excitation of atoms provides the most rigorous data for modem quantum scattering theory. The most sophisticated measurements determine quantum properties of the interaction by using laser radiation to prepare the atom prior to electron impact. The electron which scatters from the laser excited atom gains energy from the reaction, and by determining its momentum as a function of properties of the laser excited state, a complete description of the scattering process is obtained. These results will aid in the unification of different scattering models into a single theory which can be applied to all targets at all energies.In these new experiments, a new type of spectrometer recently invented at Manchester will be used to determine these properties over the complete range of scattering angles for the first time, for a range of incident electron energies. The spectrometer uses a magnetic field to steer electrons to and from the interaction region so that the momentum of all scattered electrons can be measured. Since the laser excites the atom in a magnetic field, new information will also be obtained on the laser-atom interaction, which will be compared to models of this interaction to be developed as part of this work. This new model will be applicable in many other research areas, including atom trapping, atom cooling and Bose Einstein Condensation experiments.
